Processing of Bauxite Ores To Obtain Aluminum Bauxite, the primary aluminum ore, uses the Bayer Process to extract alumina from the ore. The processing begins with crushing to 12 inch particles and wet screening, to remove some silica fines, which are generally present with bauxite.

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting.

Mining in the open pit is undertaken on 10 meter high benches. When the material is too hard to be free dug, the rock is drilled and blasted with a range of drill patterns to suit the litholog. The Open Pit is a conventional truck and shovel operation and is serviced by a large modern mining fleet of 175t and 90t haul trucks, loaded by 200t and 120t shovels and excavators.

Openpit mining Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clearcutting or burning of vegetation above the ore deposit may precede removal of the overburden. The

When minerals and deposits are found close to the surface and spread across a large distance, the best way to mine is to use the open cut mining method. In this process, the area is cleared of all topsoil and vegetation, this material is stockpiled and used later when rehabilitating the area once mining is finished.

3) PREPARATION OF FUSED ALUMINA Fused alumina is trade names of Alundum and Aloxite. Fused alumina is used to made abrasive grains. Before processing, bauxite, the crude raw material, is calcined at ~950°C to remove both free and combined water. The bauxite is then mixed with ground coke (~3 %) and iron borings (~2 %) in a pottype, electricarc furnaces for 24 hours at 2000oC. Melts the
